Software Engineer | MVP Development & XR / Spatial Computing
I build products that ship — from mobile MVPs to immersive XR experiences on Meta Quest and Apple Vision Pro. Startups hire me when speed, clarity, and quality all have to coexist.
Whether you need a React Native app with a Node.js backend live in weeks, or a mixed-reality experience with real-time AI integration, I handle architecture, build, and launch — without the complexity that usually comes with it.
Most developers write code. Fewer can take a vague idea from a non-technical founder and turn it into something investable or revenue-ready. That gap is where I work.
What I've shipped recently
→MindAura VR — an AI-driven VR therapy experience generating real-time imagery from users' emotional responses via OpenAI. Delivered in under two weeks.
→Mixed Reality art installation for a PhD thesis, deployed on Meta Quest 2, 3, and 3S using Meta SDK.
→Zoom SDK integration inside a live VR environment — described by the client as a "very complex, urgent, and challenging task" handled with ingenuity.
→Apple Vision Pro — raycast and physics-based shooting mechanics in Unity for a fully immersive visionOS build.
→Multiplayer VR school with Meta Avatars, networked voice chat, and live-session architecture.
What clients say
"Professionalism, availability around the clock, and frictionless frank and honest communication. If you are looking for someone who delivers under pressure — this is your person."
— VR Development client, 5★
"He was a life saver in a tight spot — able to handle a very complex, urgent, and challenging task with ingenuity and great initiative."
— Zoom / Unity VR Integration client, 5★
"Incredible professionalism and dedication... delivered high-quality work that exceeded my expectations. The attention to detail made the entire process seamless."

Who I work best with
→Startups that need to validate an idea fast — without sacrificing code quality or scalability
→Companies building in spatial computing, training, real estate, retail, or healthcare
→Non-technical founders who need honest timelines, plain-English updates, and a builder who can see around corners
I'll tell you what's realistic before the project starts — not after. Clear scope, milestone delivery, weekly updates without being chased.
If your idea deserves to become a real, shippable product — message me and let's talk.

Top Rated Plus | 100% Job Success | $200K+ earned on Upwork | 6,400+ hours on production XR builds
I'm a Senior Unity XR Engineer with 8+ years building immersive applications that ship, not prototypes that stall at 90% done.
What I've delivered on Upwork:
My largest engagement is a VR game project I've led since 2024: 12 interactive levels with dynamic state systems, built for Meta Quest standalone, 6,400+ hours and $240K+ billed on a single contract. The client's review: "One of, if not the best developer(s) I've ever met."
Alongside that: a HoloLens 2 mixed reality CPR training simulation, custom VR combat and interaction systems, and multiplayer VR builds.
Where I'm strongest:
Meta Quest standalone performance, holding frame budget on mobile-class hardware, where most XR projects fall apart
Custom interaction systems built on Unity XR Toolkit
Mixed Reality passthrough and spatial anchoring (HoloLens 2, Quest 3)
Multi-scene architecture and state-driven systems that survive handover to another team
Simulation and training environments, medical, industrial, educational
Platforms: Meta Quest 2 / 3 / Pro, HTC Vive, HoloLens 2, AR Foundation (ARKit / ARCore), PC VR
How I work: I respond within a few hours, I tell you upfront if your scope doesn't match your budget, and I don't disappear mid-project,the 6,400 hours on one contract are the evidence.
Send me your target headset and rough timeline and I'll come back with an honest read on whether it's a two-week build or a two-month one.

I build websites, interactive 3D applications and business systems for organisations that need reliable software built around the way they actually work.
My projects range from professional business websites and enquiry systems to product configurators, digital twin platforms and bespoke operational software. The common thread is clear: practical systems designed for real users, real workflows and long-term use.
I founded Infinitus Interactive in 2020 and remain hands-on across discovery, architecture, development and delivery. I have 10+ years of experience building websites, real-time 3D applications and production software.
Typical projects include:
- Professional business websites designed around clear user journeys and enquiries
- Custom workflow and operational systems that replace spreadsheets and disconnected tools
- Interactive 3D product and engineering configurators
- Digital twin platforms for asset visibility, inspection and decision support
- Industrial 3D applications for planning, training and review
- Unity-based tools for processing and managing large-scale 3D environments
I am usually a strong fit where:
- You need more than a generic template or off-the-shelf platform
- Your current processes rely on spreadsheets, manual work or disconnected systems
- 3D needs to connect with real data and workflows, not simply look impressive
- You want someone who can think at product level and still deliver hands-on technically
The common thread is building practical systems for real users, real workflows and long-term use.
Whether you need a professional website, a custom business system, a 3D configurator or a larger digital twin platform, send me your goals, constraints and timeline.
